4 Shams-.Sheet 4 INVENTOR United States Patent() WINDOW SASHES CharlesJ. Roos, Muskegon, Mich. Application September 27, 1955, Serial No.536,812 4 Claims. (Cl. Ztl-55) This invention relates to window sashesand openings and more particularly to an attachment by means of whichthe window sashes Aand frames of a building may be converted to lessenany concussion or explosive force on the exterior of the building.

Another object of this invention is to provide a coinbined window sashstop construction and attachment means for mounting on the upper andlower sashes of a window whereby the window glass will be held againstshattering under an explosive force.

A further object of this invention is to provide an attachment means formounting on window sashes whereby the present sash construction will beconverted to a combined storm sash and protective sash whereby the glasswill be protected against undue shattering by an exterior explosiveforce.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention consists of certain novel details ofconstruction and combinations of parts, hereinafter more fully describedand pointed out in the claims, it being understood that changes may bemade in the construction and arrangement of parts without departing fromthe spirit of the invention as claimed.

Referring to the drawings, the numeral designates generally a windowframe construction in which are mounted upper and lower sashes 16 and17, respectively. The window frame 1S includes an upper header or plate18, side frame member 19 and a sill 20. An intermediate stop 21 issecured between the inner and outer facing strips 22 and 23,respectively. The header or top plate 18 is adapted to have fixed to thelower side thereof of a metal liner which comprises a pair of plates 24and 25, which are formed integral with a U-shaped covering of the outermetal frame 2,757,420 Patented thug. 7, 1956 vmember 26, which engagesover the intermediate stop 21. t The liner formed of the plates 24 and25 and the connecting member 26, is secured to the header 18 `by anysuitable fastening means. A pair of verticallyidisposed side liners,generally indicated at 27, are disposed along the Vertical sides of theframe 15. These vertical liners 27 are formed of aligned plates 28 and29 connected together along their confronting edges by means of aU-shaped member 30 whichencompasses the intermediate stop 21. The liner27 is also formed with an upper inner flange 31 extendingright-angularly from the plate 28 and the flange 31 has extendingright-angularly therefrom, a second flange 32. The flange 32 is of alength substantially equal to the length of the upper sash 16, thepurpose for` which will be hereinafter described. The plate 28 also hasextending from the lower end portion thereof a right-angular tlange 33which extends from plate 2S a distance greater `than the flange 31. Thewide flange 32 has extending right-angularly therefrom a narrow flange34 and the length of llange 34 is substantially equal to the height ofthe lower sash 17. Plate 29 has extending right-angularly therefrom anupper relatively wide flange 3S and a right-angularly disposed flange 36extends from the flange 35. A lower narrow flange 37 extends from plate29 and a rightangular :flange 38 extends from flange 3'7. The narrowilange 31 provides a means as will be hereinafter described, whereby thelower sash may be: raised and then removed from the window frame. Thenarrow lower flange 37' also provides a means whereby the upper sash 16may be lowered and then moved outwardly and taken from the window frame.

On each inner side of the window frame 15 there is disposed a narrowtrim-strip 39 which is adapted to be secured to the adjacent edge oftrim-strip 22. The strip 39 is adapted to be disposed between flanges 32and 34. In like manner an outer trim-strip 40 is secured to the adjacentedge of outer trim-strip 23 and engages between the flanges 36 and 38.

The two sashes 16 and 17 are of like construction and each sash isformed of a rectangular frame 4l having a transparent panel l2 securedtherein. The outer side of sash 16 has mounted thereon a rectangulartransparent panel 43 which may be formed of plastic or othernonshatterable material. The panel d3 is secured to the outer side ofsash 16 by means of a rectangular metal frame 44 which is secured bymeans of screws or the like. The frame 44 is provided with aright-angular flange 45 engageable under the bottom edge of upper sash16. A similar metal frame 44 is disposed on the inner face of lower sashl' and a transparent non-shatterable panel 43 is interposed betweenframe 44 and the inner side of lower sash 17. The flange 45 of frame 4dis inverted on the lower sash 17 and engages over the upper edgethereof, as shown in Fig. 3.

An inner transparent panel 46 is disposed on the inner side of uppersash 16 and is secured thereto by means of a rectangular frame 47. Theframe 47 is formed at its lower edge with an upwardly and inwardlyinclined weather stripping flange d3 which is adapted to engageunderneath a complementary Weather stripping flange 49 carried by alower sash frame member 5t). The frame members() is secured to the innerside of lower sash 17 anda transparent non-shatterable panel 51 isinterposed between frame S0 and lower sash 17. The upper rail 52 ofupper sash 16 is provided with a cutout or rabbet 53 within which atransversely curved weather stripping member 54 is adapted to engage.The weather stripping member 54 includes a base plate 55 which is formedwith holes 56 whereby the screws or fastening members securing plate 25to plate 18, will also secure base 55 to plate 2S. The upper edge offrame 47 projects over ice N the inner side of-the'recess 53 and isadapted to be yieldingly held between the weather stripping member 54and the adjacent side of U-shaped connecting member 26. The upper rail52 also has lixed therein a yieldable weather stripping member 57 whichis adapted to be compressed against the base plate 55, as shown in Fig.3. The lower edge of frame 50 projects below the lower rail 58 of lowersash 17, as indicated at 59 and bears against a transversely curvedweather stripping member 60 carried by a plate 61. The plate 61 isformed with holes 62 through which the fastening members securing thesill plate 20 are adapted to extend.

The outer vertical edges of frame 47 extend beyond the stiles 63 ofupper sash 16 and are disposed in confronting position to the verticalsides of U-shaped connecting member 30. A U-shaped weather strippinginsert 64 is inserted in the space between the adjacent outer edgev ofstile 63 and plate 29. The U-shaped member 63 includes a straight sidemember 65, a transversely curved opposite side member 66 and a straightbight or connecting member 67. The bight 67 bears against the adjacentvertical edge of the stile 63. The projecting portion 68 of frame member47 slidingly bears between curved side member 66 and the adjacentvertical side of intermediate stop member 30. The frame member 50includes lateral inclined projections 49 which extend between theadjacent vertical side of intermediate stop 30 and the second U-shapedweather stripping member 70 which is similar to U-shaped member 64. TheU- shaped members 64 and 70 face outwardly and the space between thesides 65 and 66 is filled by means of a brous filling element 71.

The window frame structure includes an inner bottom sill member 72formed with a rabbet 73 within which the lower rail 58 is adapted toengage, and a yieldable weather stripping member 74 is carried by theinner sill member 72 within the rabbet 73.

In the mounting and use of the jamb liner hereinbefore described, theupper liner formed of plates 24 and 25 and connecting member 26, issecured in the upper portion of the window frame 15. The side liners 27are secured in the vertical sides of the frame structure whereupon theU-shaped members 64 and 70 are inserted between the adjacent edges ofupper and lower sashes 16 and 17, respectively. The U-shaped members 64and 70 may be of a length less than the length of each side member 19 sothat these U-shaped members can be inserted from below each sash. Thenon-shatterable panels 43 and 46 are secured to the upper sash 16, andsimilar panels are secured to the lower sash 17. These non-shatterablepanels which may be formed of plastic or the like and will be spacedfrom the glass panels 42 of the sashes so that a closed air pocket willbe formed on each face of the glass panel. This air pocket will form astorm window construction in combination with the non-shatterablefeatures produced by the inner and outer non-shatterable panels orsheets.
